How to compare two arrays in Mocha?

Question

When I try

expect([1,2]).to.equal([1,2])

I get

AssertionError: expected [ 1, 2 ] to equal [ 1, 2 ]

probably due to object comparison?

Use deep for a deep copy of actual attributes, e.g.

expect([1,2]).deep.to.equal([1,2]);


passes

I used `expect([1,2]).deep.equal([1,2])` – Fedorov7890 Apr 14 '22 at 15:38

The answer didn't work for me, but the comment from @Fedorov7890 did. – Simon Mar 06 '23 at 19:52
